Yesterday evening, a Tunnel Boring Machine (TBM) operated by the FEMC-Pratibha JV for contract CC-18 of Delhi Metro’s Phase 3 project made a second breakthrough at the Sarojini Nagar station! The TBM started boring from the Bhikaji Cama Place station and traveled 1105m while building 790 rings for the 58.596 km Pink line’s up-line tunnel.
The 1st breakthrough at Sarojini Nagar took place for the down-line’s tunnel just 4 months ago. For details and images see: Delhi Metro TBM Makes a Breakthrough at Pink Line’s Sarojini Nagar Station
With this breakthrough completed, all twin tunnels on the Pink line between Bhikaji Cama Place – Sarojini Nagar – INA – South Extension – Lajpat Nagar – Vinobhapuri are now complete!
Now only 8 more TBM breakthroughs are left on the Pink line:
|CC-04||CEC – CICI||Majlis Park shaft||Azadpur mid-shaft||Up-line & Down-line|
|CC-20||J Kumar – CRTG||Naraina Vihar||Mayapuri shaft||Up-line & Down-line|
